Optimizing bandwidth of DSL connections

Abstract

An arrangement is provided for optimizing the bandwidth of DSL connections. A DSL connection is established via a customer premise equipment, a copper line connecting to the customer premise equipment, and a DSL access multiplexer connecting to the copper line. The DSL connection is operated at a transmission rate that is adaptively optimized through a DSL connection optimizer based on dynamic transmission environment.
